Prepare METPO for EBI OLS submission

[turbomam]

Based on EBI OLS submission requirements, prepare METPO for potential submission to Ontology Lookup Service.

Technical Requirements to Address:

• Run ROBOT validation report and fix ERROR/WARN violations
• Verify required Dublin Core metadata completeness
• Ensure proper open license specification (CC0/CC-BY)
• Validate import chain accessibility
• Check reasoning consistency
• Verify PURL configuration and accessibility

ODK Integration:

• Update ODK configuration if needed
• Ensure src/metadata/ files are complete
• Verify release automation works properly

Quality Assurance:

• All terms have proper textual definitions
• No circular definitions
• Range information properly integrated in definitions
• Version management follows semantic versioning

Timeline:

Target completion for technical preparation within 1-2 weeks, understanding that actual OLS submission (if pursued) would take 3-6 months for review.

Update on the OLS submission path (verified 2026-06-01):

• The current path is a PR adding an entry to EBISPOT/ols4:dev/ebi_ontologies.json, not the email/spreadsheet flow in docs/ontology/adding-ontology-to-ols-draft.md (per Nico Matentzoglu in OBO Slack). That doc is now outdated on the mechanism.
• preferredPrefix must be lowercase and >=5 chars -> use metpo, not METPO (the value in metadata/ontology/ols-submission.csv).
• METPO is not among the 119 ontologies currently in ebi_ontologies.json; PURL https://w3id.org/metpo/metpo.owl resolves (200).
• Gating: OLS runs ROBOT report at load. metpo.owl currently has ~2,870 ERRORs (1,216 misused_obsolete_label, 1,216 deprecated_boolean_datatype, 438 duplicate_label) — overlaps Deprecated classes appear as root nodes in BioPortal #449. Clean those before submitting.
• Term-IRI resolution is separately broken (w3id.org/metpo term IRIs dead-end at BioPortal (HTTP 403) #450), worth fixing alongside.
